[0002] Sand and gravel wastewater flocculation is an important link in the treatment of sand and gravel processing wastewater. It mainly realizes the effective precipitation of suspended substances and pollutants in the wastewater by adding flocculants. Flocculation is to add polymer coagulation agents to the waste liquid. After these agents are dissolved, they will form polymer polymers. The structure of this kind of polymer is a linear structure. One end of the line pulls a tiny particle, and the other end pulls another tiny particle, playing a role of bonding and bridging between two particles that are far apart, making the fine particles gradually become larger, and finally forming large flocculants (commonly known as alum flowers), thereby accelerating the sedimentation of particles.

[0025] Embodiment:
[0026] Please refer to Figures 1-4, this embodiment provides a flocculation treatment device for sand and gravel wastewater, including a base 1. At one end of the top of the base 1, an adjustment tank 2 for adjusting the pH value of the sand and gravel wastewater is fixedly installed. At the other end of the top of the base 1, a mixing tank 4 for mixing the sand and gravel wastewater with a flocculant is installed. The adjustment tank 2 can transport the sand and gravel wastewater to the mixing tank 4. Inside the mixing tank 4, a mixing mechanism 5 is installed. The mixing mechanism 5 includes a stirring blade 54 for stirring the wastewater, a spraying pipe 58 for spraying the flocculant, and an air outlet pipe 55 for blowing air into the wastewater. When this sand and gravel wastewater flocculation treatment device is in use, the pH of the sand and gravel wastewater is adjusted through the adjustment tank 2 according to the performance of the flocculant, so that the sand and gravel wastewater and the flocculant can have a better flocculation effect at a specific pH value. After the adjustment is completed, the wastewater is transported into the mixing tank 4, and the flocculant is sprayed into the mixing tank 4 through the spraying pipe 58 to react with the sand and gravel wastewater. The flocculant is more easily and evenly dispersed by spraying, improving the mixing effect. At the same time, the mixing liquid is stirred by the stirring blade 54, and air is blown upward in the mixing tank 4 through the air outlet pipe 55 to prevent the suspended matter and the flocculant in the wastewater from precipitating. In summary, this device enables the flocculant to fully contact and react with the suspended matter in the wastewater through the methods of pH value adjustment, spraying of the flocculant, stirring, and blowing air.
[0027] In this embodiment, as Figure 1 shown, a water pump 21 is installed at the inner bottom of the adjustment tank 2. A drain pipe 22 is connected to the drainage port of the water pump 21. One end of the drain pipe 22 passes through the outer side of the adjustment tank 2 and then a flow control valve 3 is installed. After passing through the flow control valve 3, the drain pipe 22 passes through the outer side of the mixing tank 4 and communicates with the inside of the mixing tank 4, so that the wastewater whose pH is adjusted inside the adjustment tank 2 can be transported into the mixing tank 4 and the quantity can be controlled through the flow control valve 3.
[0028] In this embodiment, as Figure 1 、 Figure 2 and Figure 4 shown, a cross plate 51 is installed on the mixing mechanism 5. A motor 52 is installed at the top of the cross plate 51. A rotating shaft 53 is installed at the bottom of the cross plate 51. The motor 52 drives the rotating shaft 53 to rotate. The bottom of the rotating shaft 53 is sleeved and installed on a sealing bearing 42 on a connecting pipe 41, so that the rotation of the rotating shaft 53 is not affected when the connecting pipe 41 is communicated with the rotating shaft 53.
[0029] In this embodiment, as Figure 1 、 Figure 2 and Figure 3As shown in the figure, a chemical agent tank 6 is installed on the outer side surface of the stirring tank 4. The top of the chemical agent tank 6 is connected with a bent pipe 61. One end of the bent pipe 61 is connected with the top end of a cross plate 51. A clamping groove 56 is formed at the bottom of the cross plate 51. An annular sleeve 57 is clamped at the center of the clamping groove 56. Spraying pipes 58 are connected in four directions on the outer ring surface of the annular sleeve 57. The spraying pipes 58 are all clamped inside the clamping groove 56. One end of the bent pipe 61 is connected with the spraying pipes 58, and the interiors of the four spraying pipes 58 are communicated through the annular sleeve 57. Spraying holes are formed at the bottom of the spraying pipes 58. The flocculant is conveyed into the spraying pipes 58 through a pump inside the chemical agent tank 6, so that the chemical agent can be sprayed through the spraying pipes 58, improving the mixing effect of the wastewater and the chemical agent.
[0030] In this embodiment, as Figure 1 and Figure 4 shown, stirring blades 54 are installed on the outer ring surface of a rotating shaft 53. Air outlet pipes 55 are symmetrically installed on both side surfaces at the bottom of the rotating shaft 53. Air outlet holes are evenly installed at the top of the air outlet pipes 55. The inner sides of the air outlet pipes 55 communicate with the interior of a connecting pipe 41 through the inner side of the rotating shaft 53. A connecting seat 7 is installed at one end of the outer side surface of a base 1. An air pump 71 is installed on the top of the connecting seat 7. An air pipe 72 is connected to the air outlet port of the air pump 71. One end of the air pipe 72 is embedded inside the base 1 and then connected with the connecting pipe 41. A solenoid valve is provided at the connection between the connecting pipe 41 and the air pipe 72 and the valve body automatically closes after the air pump 71 is turned off. Thus, after the air pump 71 inflates the air pipe 72, the connecting pipe 41 inflates the interior of the air outlet pipes 55, causing the air outlet pipes 55 to blow air into the wastewater, promoting the mixing between the flocculant and the wastewater suspension.
[0031] Working principle: When the sand and gravel wastewater flocculation treatment device is in use, first, the pH value of the sand and gravel wastewater is adjusted through an adjustment tank 2 according to the performance of the flocculant, so that the sand and gravel wastewater and the flocculant can have a better flocculation effect at a specific pH value. Then, the wastewater with the pH adjusted inside the adjustment tank 2 is conveyed into the stirring tank 4. During this process, metered conveyance can be carried out through a flow control valve 3. At this time, the flocculant is conveyed into the spraying pipes 58 through a conveying pump inside the chemical agent tank 6, so that the chemical agent can be sprayed through the spraying pipes 58, improving the mixing effect of the wastewater and the chemical agent. Then, a motor 52 drives the stirring blades 54 to stir the wastewater. And after the air pump 71 inflates the air pipe 72, the connecting pipe 41 inflates the interior of the air outlet pipes 55, causing the air outlet pipes 55 to blow air into the wastewater, promoting the mixing between the flocculant and the wastewater suspension. In summary, the device enables the flocculant to fully contact and react with the suspended substances in the wastewater through the methods of pH value adjustment, spraying of the flocculant, stirring, and blowing.
[0032] All the technical features in this embodiment can be freely combined according to actual needs.
[0033] The above embodiments are preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious substitution without departing from the concept of the technical solution is within the protection scope of the present utility model.
